I have several Permedia 2 boards from varying manufacturers, but none of the branded or reference drivers have a clear way of disabling v-sync. I've tried:
- ELSA Win98 Driver v0203-0013
- Diamond Driver Release v1098
- 3Dlabs reference driver v2105-0366

Can this be done via a control applet, registry entry or environment variable?

While I'm at it, I'm trying to do the same for my Rendition Verite V1000/V2x00 cards. Some drivers such as the reference v3.0 beta 5 have a 'No V-Sync' checkbox option in the display settings applet, but unchecking this, saving and opening the applet again finds the box still checked. Again, is there a registry entry or environment variable I can apply? If so, would that be at application or system level?

Powerstrip?

Powerstrip is discontinued and you can no longer buy a license key, AFAIK, though the unregistered version may do what you want .

Powerstrip was shareware utility, so it can be used before purchase, but maybe it won't help anyway. If it can't be purchased and discontinued, then it's "abandonware" and you know what to do *wink wink nudge nudge*

Thanks. I know of Powerstrup but never think to use it. I will give it a go and post an update.

I can confirm that Powerstrip can disable Vsync for Direct3D and enable it for OpenGL.

I saw that too, in version 3.9. I tried 2.78 to begin with, but that offered no such options. The OpenGL/DirectX settings buttons on the toolbar do nothing.
I tried 3.9 and got the same options as you. Does that imply v-sync for OpenGL is disabled by default? Either way, check the 'Enable vertical sync' option did not affect performance results for GLQuake, Quake II and Unreal with OpenGLDrv. Either vertical sync cannot be enabled/disabled on the cards (even though the option is there) or the setting in PowerStrip doesn't work correctly (I.e overridden by application).
